TL;DR: In this paper, the decomposition filters are switched and used according to which an input signal is for, a top-field or a bottom-field decomposition filter, and the output signal is selected according to the input signal.

TL;DR: A moving picture editing apparatus includes a picture extracting unit that extracts pictures of a predetermined range including a picture subsequent to a coupling point from encoded data to be coupled; an adjustment-information generating unit that generates adjustment information for adjusting values of information to be continuous from/to inside to/from outside the predetermined range upon decoding, from among information included in headers of the pictures of the picture extracted by the picture extraction unit; and a re-encoding unit that adds the adjustment information generated by the adjustment- information generating unit to the headers of images from the picture extractor, and re

TL;DR: In this paper, a decoding apparatus in accordance with H.264 is presented, where the POC type is determined as "1" and a recovery point SEI is detected, and the maximum frame number MaxFrameNum is set as the initial value of the frame number offset (FrameNumOffset).

TL;DR: In this paper, the downsampling low-pass filter is designed together with an associated up-sampling lowpass filter, such that the first downsample low pass filter and the upsample low passing filter substantially satisfy perfect reconstruction filter bank condition, and such that a sum of the group delay of the first down-sample low pass and a normalized filter obtained by making the sum of all the coefficients of the upsampling lower pass filter equal to 1 is substantially equal to an integer number at frequency ω=0.
